Description

Detailed description of the invention

The present invention relates to a shower device that utilizes hot water waiting water before the hot water temperature from a water heater reaches a temperature suitable for use among shower devices mainly used in a bathroom of a house.

As a water-saving technique related to the shower device, a method of temporarily stopping the water flow at the hand of the shower head is generally used. However, in “JP 2007-120083”, the hot water temperature from the water heater is a temperature suitable for use. Technology has been developed that utilizes hot water awaiting before reaching the level. However, this method could not eliminate hygienic concerns due to the decay of accumulated water.

Problems that the device tries to solve

It is said that global warming is progressing rapidly due to the emission of carbon dioxide, etc., when the global environment is greatly damaged. Among them, the ratio of the consumer sector is very large in energy consumption, and there is an urgent need to reduce energy in the home. In household energy consumption, the ratio of hot water supply is very high along with heating and lighting. Various water-saving tools have been sold so far, but it has not been possible to significantly reduce hot water supply. When using hot water, a large amount of hot water with low hot water temperature must be thrown away until the hot water temperature is suitable for use, and this has become enormous depending on the number of times. Reusing hot water is the definitive solution, but hot water needs to be temporarily stored, and at the stage of storing it, there is no possibility of causing problems such as water decay. It was. An object of the present invention is to provide a multi-functional and useful shower device that can be installed in a house or the like relatively easily, can use hot water without fear of water rot, and the like.

Means for solving the problem

1 shows an embodiment, the multifunctional water-saving shower device of the present invention mixes hot water supplied by a hot water supply pipe from a water heater and water supplied by a water supply pipe from a water main, and discharges water. A water storage tank 3 provided in the middle of a pipe leading to a water discharge port such as a shower head, a valve for switching according to the temperature of hot water passing through the water storage tank 3 installed in the interior, Is constructed by a mechanism for inducing the ejector effect, a photocatalyst paint applied to the inside of the water storage tank 3, and a water discharge head 7 for switching the water flow by the hand switch 6. When using a water heater, the hot water supplied through the mixing faucet 1 usually takes time to rise in hot water temperature, and the time required for the rise may be about 1 minute. During this time, the hot water waiting for low temperature could not be applied to the body, and in most cases it was drained as it was and was very wasteful. This low temperature hot water is temporarily stored in the water storage tank 3 by using a valve that switches temperature sensing such as a thermostat. When the hot water temperature rises, it is automatically guided to the water discharge head 7 by the switching valve. At that stage, the heat sensitive display mechanism 5 of the water discharge head 7 displays the hot water temperature. At this point, hot water can be used as a shower as it is, but when the hot water supplied by the hand switch 6 is returned to the water storage tank 3, the hot water waiting water stored by the mechanism that induces the ejector effect inside the tank is sucked up. Then, the temperature is returned to the spout head 7 at an appropriate temperature and can be applied to the body. The ejector effect is that the pipe that passes the hot water returned from the water discharge head is processed into a narrow section, and the pipe is connected to the hot water storage section to temporarily increase the hot water passage speed. Thereby, it becomes possible to suck up hot water. The stored hot water can be stored without being spoiled by the photocatalyst paint applied to the inside of the storage tank 3, and chlorine contained in the tap water can be reduced, so that a gentle shower can be used. The photocatalyst requires light, but the water storage tank 3 is made of a light-colored translucent plastic such as milky white, and functions well with ordinary lighting in a bathroom or the like.

In order to further enhance the water saving effect, the water discharge head 7 is provided with a mist generating mechanism 8. This is composed of a plurality of water spray plates that rotate in opposite directions via an impeller by water flow pressure, and can generate mist with a small amount of water. When investigating the usage of showers at normal homes, there are many cases where showers are left unlit even when there is no need to take a shower. This is to prevent the body from being cooled, especially in winter, and even in other seasons, once the faucet is closed, it dislikes the sandwich effect that cold water suddenly mixes with the hot water that had been used until then. . Therefore, when there is no need for a shower, switching to mist enables significant water saving without lowering the hot water temperature of the water heater. In recent years, there is a tendency to enrich bath time by using a fragrance, etc., so that the water discharge head 7 can contain cartridges of various drugs such as a fragrance and replace the cartridge. You can enjoy various effects.

As shown in Fig. 1, it is a device that can be replaced at the shower hose connection part of a mixed faucet with a shower and a spout for a bathtub provided in a bathroom, generally connected with a cap nut. The shower hose can be removed and the device can be easily installed. The water storage tank 3 is shaped like a triangular prism with a right triangle as the bottom so that it can be easily installed in the bathroom, and can be easily placed in the corner of the bathroom. Functions such as a soap holder can be added to the top and side. Unlike a normal shower hose, the pipe connecting the water storage tank 3 and the water discharge head 7 is divided into three sections. The first is a part that directly sends hot water with a sufficiently high temperature from the mixing faucet 1 by a switching valve inside the water tank 3, and the second is to use hot water waiting water stored in the water tank 3. A part for returning hot water from the water discharge head 7 to the water storage tank 3 by the hand switch 6 installed in the water discharge head 7, and a third part is sucked up by the ejector effect by the water returned from the water discharge head 7 to the water storage tank 3 by the hand switch 6. This is the part that returns the hot water mixed with the water waiting for hot water to the water discharge head 7.

The heat-sensitive display mechanism 5 provided in the water discharge head 7 utilizes a heat-sensitive paint that changes from blue to red as the hot water temperature rises, so that the appropriate temperature can be easily known. Similarly, the cartridge built-in function provided in the water discharge head 7 is the one in which the drug is filled in a finely divided structure so that the drug gradually melts in the water passing portion inside the water discharge head 7. And can be easily replaced by opening the lid. Accordingly, a wide variety of drugs such as various fragranced fragrances, various medicinal bathing agents, drugs such as vitamin C, water quality improving agents, and detergents for washing the body can be used.

Effect of device

As described above in the detailed description, the present invention can maximize the water-saving effect in the shower device, and can also reduce waste due to the user's act of leaving it out. In addition, it has a variety of shower functions that have been highly requested in recent years, and you can enjoy a healthy and healthy bath time that is gentle to the skin. Since the attachment is easy, the shower device can greatly reduce the utility cost and the carbon dioxide emission significantly and easily compared to the conventional case.
